Grace O'Connor
- Voiced by: Kikuko Inoue
Grace is Sheryl's manager from the Macross Galaxy Fleet and appears as a person with a gentle, calm attitude. She often upsets her employer, despite having considerable abilities.
The main antagonist of Macross Frontier, Grace was a scientist aboard the 117th Long Distance Research Fleet, working alongside Dr. Mao and Ranshe, until the fleet's destruction by the Vajra. She now hopes to use the Vajra as a tool for galactic domination.
One name she uses is Grace Godunawa.
- Adaptational Heroism: Performs a Heel–Face Turn in the movies and is shown as a protagonist in Macross 30: The Voice that Connects the Galaxy.
- Assimilation Plot: Her ultimate goal is to absorb everyone into the Vajra Hive Mind, with herself in control.
- Bitch in Sheep's Clothing: Beneath her demure, reliable secretary facade is a twisted manipulator that enjoys toying with others, whether it be to advance her schemes (Sheryl, Ranka), or sadistic amusement (opening Michel's wounds regarding the death of his sister).
- Big Bad: Though we don't learn it for quite a while. Because, seriously, who expected an idol manager to be a budding Galactic Conqueror? Or for that matter, the character voiced by Kikuko Inoue to be outright evil?
- Cybernetics Eat Your Soul: Justified and done willingly. Grace deletes her feelings for Sheryl at some unspecified time to keep it from getting in the way of her plans. All There In The Drama CD.
- Heel–Face Turn: Movie only, as getting shot up severs her connection to the Galaxy's Omniscient Council of Vagueness, allowing her to show that she really does care for Sheryl.
- Happens also in the Sheryl: Kiss in the Galaxy manga, this time it's seeing Sheryl in love that breaks Galaxy's hold on her.
- Hive Queen: Temporarily, until Ranka and Sheryl break her control over the Vajra.
- I Am Legion: She is actually host to a number of intelligences in one body.
- Mad Scientist: Oh, sweet Jesus, VERY.
- Traitor Shot: The moment you start seeing that incredibly unpleasant, smug expression she gets when something is amusing her, you know she's not to be trusted.
- Revenge: She states that part of the reason she's doing what she is, is to get back at Dr. Mao for some unspecified reason.
- The Sheryl: Kiss in the Galaxy manga implies that part of the reason she wants to get back at the Vajra is the attack on Gallia-4 happened on her wedding day.
- You Have Outlived Your Usefulness: Subverted; Leon, and by extension, the Frontier fleet and Vajra, has outlived theirs.
- Walking Spoiler: It's pretty tough to talk about her character without revealing the unexepectedly large role in the plot she plays.
Brera Sterne
- Voiced by: Soichiro Hoshi
The mysterious pilot of the crimson VF-27 Lucifer that Alto encounters for the first time inside a Vajra battleship, Brera seems to know how to play the first part of Ranka's song "Aimo" using a harmonica carried around his neck, claiming the song is but a fragment of his past. After saving Ranka from a wild beast attack, the injuries Brera sustained reveals he is also a cyborg. He's assigned to become Ranka's bodyguard by the Frontier government after he reveals he is a major of the Macross Galaxy's Antares Squadron, who was supposedly missing-in-action alongside the Macross Galaxy. Brera harbors a great deal of concern for Ranka's well-being, but doesn't exactly know why, but describes the feeling he gets from her songs as being enveloped in a universe that accepts him instead of rejecting him.
Brera is, in fact, Ranka's biological older brother Brera Mei, the son of Ranshe Mei. How he survived the destruction of the 117th Long Distance Research Fleet is unknown, but his body is rebuilt into a cyborg by the Macross Galaxy years later.
- Badass Longcoat: In The Movie.
- Battle Butler: To Sheryl in The Movie.
- Blade Below the Shoulder: He's got a few melee weapons built into his body.
- Brainwashed and Crazy: Or rather, being "remote-controlled" and crazy. Subverted by series' end.
- Cyborg: Apparently it was a common practice aboard the Galaxy Fleet. It gives him some obvious advantages in combat, but also makes him susceptible to mind control through his implants.
- Death by Adaptation: In the Wings of Goodbye.
- Expy: of Lynn Kaifun from the original series, both being relatives of one of the main female leads (see Long Lost Sibling) and with both having subtle romantic overtones in their respective relationships with both girls, if the Sheryl: Kiss in the Galaxy manga is any indication. Subverted, however, in that Brera is anything but the staunch pacifist Kaifun was and unlike the latter, he actually does get redeemed near the end.
- Heroic Sacrifice: Kills off the Galaxy Fleet leaders, by ramming his plane into their server.
- Long Lost Sibling: He's actually Ranka's elder brother.
- Mr. Fanservice - The front of the skintight body suit he usually wears is cut out and constantly showing off most of his chest, starting from the bottom of the neck all the way to a good distance below his navel.
- Navel-Deep Neckline: His main outfit leaves a huge gap in his torso.
- Pre-Mortem One-Liner: "Be scattered to the ends of the galaxy", a nod to the line Ranka says before she starts singing.
- Sissy Villain: Started out as one of the antagonists, and wears a rather effeminate outfit with a Navel-Deep Neckline and high-heels, his pilot outfit is purple and also with high heels, and his jet fighter is magenta-colored all over.
